John Miller - AC-DOJ President (Senior Criminalist)

Although not as well known as their fictional counterparts on television, the more than 200 criminalists for the California Department of Justice are the real-life crime scene investigators (CSI) who provide prosecutors with that missing link between victim and perpetrator.

Their association is led by John Miller, whose 27 years as criminalist with DOJ has witnessed the growth of DNA technology from its infancy, when evidence submitted to crime labs depended so much on size and condition, to its maturity when even the most microscopic sample taken 30 years ago can be amplified to reveal the culprits in some of the state’s most grizzly crimes.

The Association of Criminalists at the California Department of Justice that Mr. Miller is president of divides its work into 10 specialties: Crime scene response (homicides), DNA, blood alcohol, clandestine lab response, firearms and tool marks, latent-print (fingerprints), photoelectric (audio and visual surveillance), questioned-document examinations (forgeries), solid-dosage drug analysis, trace analysis, and digital evidence. Association members are the crime labs for 48 of California’s 58 counties.

The son of an Air Force jet mechanic, Mr. Miller was born on a military base in Japan, but grew up in Modesto where his family eventually settled. He graduated from Sacramento State University with a degree in biology and a minor in chemistry and has received additional training at DOJ’s California Criminalistics Institute in Sacramento.

Mr. Miller, his wife, and three children continue to make their home in Modesto. He has been president of the Association of Criminalists-Department of Justice since 1994. In that job, he lobbies for improved working conditions and adequate compensation for the members who provide the indispensable central thread of criminal prosecution.
